Since I already had success growing a pineapple plant from the scraps, it didn’t take an abnormally large leap of faith to think this might work with other leftovers. I first decided to try this on the ends of some organic green onions. These are by far one of my favorites, but so expensive! Not any more… they started to grow within a day once I put them in water! After a week or so they had large enough roots to transfer to a pot. They are now growing steadily and we can give a haircut to the plant as needed for an endless (and free) supply of fresh green onions throughout the year.
